Abstract
Description
Technical Field
[0001] This utility model relates to the field of casting mold technology, and in particular to a concrete mold for a perforated flower wall in a water purification plant. Background Technology
[0002] As a key structure in surface water treatment plants, the flocculation sedimentation clear water tank requires a water flow buffer wall between its folding plate zone and sedimentation zone. The perforated flower wall requires a large number of concrete blocks, and traditional methods result in low formwork turnover. Moreover, the traditional mold-making method relies on fixing the formwork in advance, but this can easily lead to grout leakage at the joints. Furthermore, the concrete blocks are easily damaged when removing the formwork, affecting the appearance quality after completion and failing to meet the concept of achieving high-quality results in one go. The construction process can also lead to uneven masonry surfaces, affecting the service life of the perforated flower wall and increasing the cost of later repairs and maintenance.
[0003] In the construction of flocculation sedimentation clear water tanks in waterworks, perforated concrete walls serve as buffer walls between the folding plate zone and the sedimentation zone, requiring a large number of precast clear water concrete blocks with high precision. Traditional construction methods typically use wooden or ordinary steel formwork erected on-site, which presents the following prominent problems:
[0004] 1. Low turnover rate: The templates are mostly assembled once or a limited number of times, and the disassembly and assembly are frequent, resulting in large input of labor and materials, making it difficult to meet the needs of mass prefabrication.
[0005] 2. Grout leakage and geometric deviation: The joints of the templates are only fastened by nails or bolts, which cannot completely eliminate the gaps. During pouring, the cement grout overflows, causing the edges and corners of the precast blocks to be damaged and the surface to have air holes. After the walls are built, the flatness of the wall surface is poor, which affects the appearance and the flow conditions.
[0006] 3. Demolding damage: After the formwork is bonded to the concrete, it needs to be pried off, which can easily cause the edges and corners of the precast blocks to be damaged, resulting in chipped edges and corners; subsequent repairs increase the number of procedures and costs, and do not meet the goal of "one-time success and high-quality repair without maintenance".
[0007] 4. Difficulty in dimensional control: Traditional formwork reinforcement systems lack rigidity, and long, thin-walled components are prone to deformation under vibration and concrete lateral pressure, causing the thickness and hole position deviation of precast blocks to exceed the standard, affecting the overall assembly accuracy and service life of the perforated flower wall.
[0008] 5. High maintenance costs: Due to the poor surface quality and inconsistent size of the precast blocks, secondary leveling, patching, and even rework are required on site, which significantly increases the maintenance workload after the clear water tank is put into operation.
[0009] Therefore, for those skilled in the art, a new type of mold for producing concrete blocks with high turnover rate and quick demolding without damage is particularly important. Utility Model Content
[0010] The technical problem to be solved by this utility model is to provide a concrete mold for perforated flower walls in water purification plants, which achieves high turnover rate and quick demolding without damaging the concrete blocks, thereby increasing the service life of the perforated flower walls and reducing the later maintenance costs.
[0011] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0012] A concrete mold for a perforated flower wall in a water purification plant includes an inner mold, an outer plate set outside the inner mold, and fixed-length steel bars that tighten the outer plate.
[0013] The inner mold includes an inner top plate, an inner side plate whose upper edge is connected to the inner top plate, and an inner base plate that extends outward from the lower edge of the inner side plate.
[0014] The outer side plate and the outer edge of the inner side plate base are connected by a hinge.
[0015] A further improvement of this utility model is that the inner side plate is fixed to the inner top plate and the inner side plate to the inner base plate using steel nails.
[0016] A further improvement of this utility model is that the hinge is a ball bearing hinge.
[0017] A further improvement of this utility model is that: the outer side plates are configured as four, and the vertical edges of the outer side plates are all chamfered at 45°.
[0018] A further improvement of this utility model is that the fixed-length steel bar includes a square frame and handles on both sides of the frame.
[0019] A further improvement of this utility model is that the fixed-length steel bar is fixed by welding, and the steel bar type is C12.
[0020] A further improvement of this utility model is that: anti-slip rubber pads are provided on the inner surface of the contact positions between the fixed-length steel bar and the four corners of the outer side plate.
[0021] The technological advancements achieved by this utility model due to the adoption of the above technical solution are as follows:
[0022] 1. This utility model achieves high turnover rate and quick and damage-free demolding of concrete blocks through the hinge connection between the inner side plate and the inner base plate.
[0023] 2. The outer side panels of this utility model use fixed-length steel bars with handles for tight clamping. The position of the clamps can be adjusted flexibly to ensure that the gaps around the outer side panels are tight and there is no leakage of grout.
[0024] 3. The templates, hinges, steel bars, and anti-slip pads used in the various structural components of this utility model are all common materials used in production and daily life, resulting in low manufacturing costs. Attached Figure Description
